I just find that the dark-characters-on-light-background dial presentation is puzzlingly at odds with the general aircraft instrumentation trend of light-on-dark. Even an un-illuminated relatively large pale area affects the low-contrast perception of items around it in dark conditions. When cockpit/operational area detail gets prescribed even down to the use of screw-heads of dark matt finish, the R1155 scale seems a glaring exception- even if only carefully and briefly illuminated by the use of a torch/gooseneck etc. when needed, something in the style of the PCR's light-on-dark scale would surely be less of a reflective liability. The radio designer couldn't be certain that every installation would be "under the hood" or "down below"- in the end, it seems to have been decided/realised that exhaust flare put any other source of illumination literally in the shade, but when there's a philosophy of "if it can be controlled, it should be controlled" (hence apocryphal tales of ARP wardens telling folk to extinguish cigarettes and so on!), the R1155's scale does seem contradictory.
